Elabela(19-32) 是与 apelin 受体 (APJ) 结合的 ELABELA (ELA) 活性片段。Elabela(19-32) 激活 G_αi1 和 β-arrestin-2 信号通路，EC₅₀ 分别为 8.6 nM 和 166 nM。Elabela(19-32) 诱导受体内在化，降低动脉压，对心脏产生正性肌力作用。

Elabela(19-32) is an active fragment of ELABELA (ELA) that binds to apelin receptor (APJ). Elabela(19-32) activates the G αi1 and β-arrestin-2 signaling pathways with EC 50 s of 8.6 nM and 166 nM. Elabela(19-32) induces receptor internalization and reduces arterial pressure, exerts positive inotropic effects on the heart.

IC50: 8.6 nM (Gαi1) and 166 nM (β-arrestin-2)

Elabela(19-32) (analogue 3) has a Ki of 0.93 nM for binding of radioligand apelin-13[Glp, Nle, Tyr][I].
Elabela(19-32) has an EC50 of 36 nM in HEK293 cells transiently expressing the HA-hAPJ receptor. Elabela(19-32) is slightly less potent than apelin-13 and ELA to elicit receptor internalization.
Elabela(19-32) (0.001 to 0.3 nM) has an EC50 of 1.5 pM in inducing changes in left ventricular developed pressure (LVDP) on the Langendorff perfused isolated rat heart.
has not independently confirmed the accuracy of these methods. They are for reference only.

Elabela(19-32) (analogue 3) is rapidly metabolized in rat plasma (t 1/2 <2 min).
has not independently confirmed the accuracy of these methods. They are for reference only.
